what the hell was that?
I had to watch over and over again the couple of seconds where he makes the decision to pick up the stool and beat himself. He carries out his plan after glancing down only a fraction of a second to grab the stool. The decision happens very quickly, almost as if a voice in his head had been telling him from the beginning, "Pick up the stool! Pick up the stool!" I am fascinated and uncomfortable. (And lsughing a little.)
